Book excerpt: Expectations, Employment and Prices brings Keynesian economics into the 21st century by providing a new paradigm that explains how high unemployment could potentially persist forever without a little help from the government. The book fills in logical gaps that were missing from Keynes' General Theory of Employment Interest and Money by reconciling some of its key ideas with modern economic theory. Central bankers throughout the world are talking now about developing a second instrument of monetary policy in addition to controlling the interest rate. Roger Farmer directly addresses this issue and offers new creative monetary policy proposals and suggestions for the design of new financial institutions for the 21st century.
